SASI-I-FASTENER.

Specification of Letters Patent.

Patented Nov. 12, 1907.

Application filed March 12.1906. Serial No. 305.534.

To all whom it may concern:

Be it known that 1, JOHN C. 0 Norm, a citizen of the United States,residing at Hamburg, in the county of Erie and State of New York, haveinvented a new and useful Improvement in Sash-liasteners, of which thefollowing is a specification.

This invention relates to improvrnnents in sash fasteners and moreparticularly to fasteners for securing removable storm sashes andscreens in place in the window frames.

The primary object of the invention is to provide a simple andinexpensive and easily operated device which can be readily appliedeither outside or inside of the storm sashes and screens and which willhold the same securely in position and will prevent rattling thereof.

A further object of the invention is to make a fastener so simple inconstruction and in mode of attachment that no fitting or cutting ofeither the sash or window frame is required in applying the same, andthe ordinary unskilled householder can easily apply lghe device.

The fastener also possesses the advantage that it can be used forfastening either sliding window sashes or screens to securely hold thesame at any point to which they may be raised or lowered.

In the accompanying drawings: Figure 1 is an outside elevation of awindow frame and a storm sash secured therein by sash fastenersembodying the invention. Fig. 2 is an enlarged perspective view of oneof these fasteners and the adjacent parts of the window sash and frame.Fig. 3 is an enlarged horizontal section, partly in plan, of a portionof a window frame and storm sash, showing the fastener secured upon theinner side of the sash. Fig. 4 is an. enlarged fragmentary horizontalsection, partly in plan, of a window, showing the fastener applied tothe upper sliding sash.

Like letters of reference refer to like parts in the several figures.

A represents the frame of a window of usual construction, I) the outercasing, c the blind stop, d the jamb, e

the parting strip, and f the upper window sash thereof. G represents astorm window sash fitted, as usual, within the outer casing b andresting against the blind stop 0 of the window frame and held inposition therein by fasteners H forming thesubject of this invention.Window screens are commonly secured in the window frame in the sameposition as the storm sash shown, and it will be understood that whilethe fastener is illus- I trated in the drawings in connection with astorm sash it is equally welladapted for securing window screens. Thefastener, which is in the nature of a turn button,

, has a flat body portion h, through a central hole in which a screw hor other securing device is driven into the rail of the storm sash topivotally secure the fastener thereto, and has fastening arms h and hextending therefrom in opposite directions. One arm h extends from thebody portion h in the plane thereof, while the other arm h" is bentoutwardly or extends at an angle to the said body portion h. These armsh and h have sharp edged projections h" and h extending laterallytht-refrom, preferably, though. not necessarily, in the same directionfrom the body portion. h. The arm 7& also has at its outer end, at theside opposite to the lateral projection 7%, a driving lug or part hprojecting outwardly or an angle to the plane of said arm, the purposeof which will be hereafter more fully explained.

The fastener of the form shown can, if preferred, be readily made from aflat sheet metal stamping bent or pressed into shape.

This fastener is intended for use on either the outer or inner sides ofstorm sashes or screens, as occasion may require. When the sash orscreen rail is of less thickness than the outer casing of the windowframe, as shown in Figs. 1 and 2, the fastener is secured to the outerside of the sash G and the sharp edged projection .of the arm h of the.fastener is driven into the Wood of the outer casing b by a blow with ahammer on the driving lug h. essary to similarly strike the free armthereof a blow or two to release the holding projection. if the outercasing b is sufiiciently thicker than the sash G the offset projection71 of the other fastening arm k can be driven into the wood of thecasing. The former method, however, has been found preferable to this,as the projection h of the arm 72- will cut into the casing farther fromits outer edge and a securer hold is insured.

Where the storm sash or screen equals or exceeds in thickness the outercasing of the frame, the fastener is secured to the inner side of thesash, as shown in Fig. 3, and when so used, the offset projection k ofthe arm k is driven into the blind stop 0 of the window frame to holdthe storm sash or screen in position by a blow or two on the rear sideof said projection. In this application of the device the arm h and itscutting projection cannot be used to hold the sash or screen in placeas, if driven down, this arm and its cutting projection would enter thespace between the inside of the sash and the blind stop. This projection7L5 .can be readily driven into the blind stop by a blow with a hammeron the inner edge of the offset arm h of the fastener, which projectsoutfrom the face of the sash so that it can be easily struck.

As shown in Fig. 1, when the fasteners are placed on the right and lefthand sides of a storm sash or screen, the arms of the fasteners on oneside of the sash extend in an opposite direction from the correspondingarms of the fasteners on the other side of the sash, that is, in theconstruction the fastening arms h at the left of the window extendupwardly, while on the right they extend downwardly and the converse istrue of the arms h If desired, this could be avoided by constructing Torelease the fastener it is only nec-' the device in two iorms, onehaving the lateral projections extending to the right of the body andthe other to the left. The fastener can also be placed on the slidingwindow sashes or screens for locking them in any position. Such aconstruction is shown in Fig. 4 in which f represents the upper slidingsash of a window of ordinary construction. The fastener is secured onthe inner side of the sash and its offset lateral projection if isdriven into the parting strip a. If the fastener is placed on the lowersash, the cutting edge is driven into the inside stop of the windowframe. By this means the windows can be raised or lowered to any desiredpoint and then securely locked in position against all further movementuntil the fastener is released.

I claim as my invention:

1. A window fastener comprising a body pivoted to one member of awindow, an arm extending from said body substantially in the planethereof, a sharpened projection extending from one side of said arm andadapted to be driven into another member of the window, and a drivingportion on said arm opposite to said sharpened projection, substantiallyas set forth.

2. A window fastener comprising'a body pivoted to one member ofa'window. an arm oitset from said body, and a sharpened projectionextending from one side of said Witnesses EDWARD C. HARD, A. L. McGee.
